Description

Technical Field

[0001] This utility model relates to the field of track construction technology, specifically a mobile shield tunnel segment rapid inspection device. Background Technology

[0002] Tunnel boring machine (TBM) segments are the main assembly components in TBM construction, forming the innermost barrier of the tunnel and bearing the responsibility of resisting soil pressure, groundwater pressure, and other special loads. To ensure the stability of the TBM segments during installation, key dimensions such as width, thickness, and arc length need to be measured after production to guarantee the quality of the assembly. With the increasing development of industrial cameras, they are increasingly used for automated and non-contact measurement. However, typical camera mounting platforms have fixed camera positions, limiting their ability to measure only a single product. Furthermore, the placement of positioning points is based on the camera's location, resulting in limited applicability. Changing the positioning point's location necessitates reprocessing the camera's mounting components, which is time-consuming and labor-intensive.

[0003] Traditional methods for inspecting tunnel shield segments typically employ vernier calipers, steel tape measures, or flexible measuring rulers. These methods are inefficient, have low accuracy, and the results are highly dependent on the skill level of the inspectors, making it difficult to guarantee quality. Furthermore, they are labor-intensive. Currently, more common high-precision measurement methods utilize trackers and scanners, but these still require manual operation. Utility Model Content

[0004] The present invention aims to provide a mobile shield tunnel segment rapid inspection device, which can adjust the position and angle of the positioning camera and the measuring camera to better capture images of different parts of the shield tunnel segment and meet the inspection task's need for shooting from different angles.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A mobile shield tunnel segment rapid inspection device includes an AGV trolley, a base fixedly connected to the top of the AGV trolley, a platform base plate fixedly installed on the top of the base plate, a projector installed in the middle of the platform base plate, and first industrial slide rails fixedly installed on both sides of the platform base plate. An industrial slider is slidably connected to the first industrial slide rail, and a rotating gimbal is detachably fixed to the top of the industrial slider. A measuring camera is detachably fixed to the top of the rotating gimbal.

[0007] A raised shaft is fixed to one side of the top of the platform base plate. A ball table base is fixedly installed at the top of the raised shaft. A universal ball is rotatably installed inside the ball table base. A second industrial slide rail is fixedly installed on the top of the universal ball. Positioning cameras are slidably connected to both ends of the second industrial slide rail.

[0008] Based on the above technical solution, its operating principle and the resulting technical effects are as follows:

[0009] When inspection is required, first install the measuring camera on the first industrial guide rail. Unlock the industrial slider by turning the slide rail handle, allowing the industrial slider to move to the appropriate position on the first industrial slide rail. Then, tighten the slide rail handle to fix the industrial slider. This fixing method is convenient and allows for adjustment and locking of the industrial slider's position as needed, ensuring stable fixation in any desired position. Next, turn the pan-tilt knob interface to rotate the pan-tilt head. Rotating the pan-tilt head allows for easy adjustment of the measuring camera's field of view to better capture images of different parts of the tunnel segment, meeting the inspection task's need for shooting from different angles. Then, turn the damping handle to allow the omnidirectional ball to rotate in multiple directions within the ball mount, flexibly adjusting the positioning camera's posture in space and changing its angle and position from all directions to adapt to the positioning requirements of tunnel segments of different shapes and sizes. Finally, start the AGV (Automated Guided Vehicle), which uses laser navigation and can create its own map and drive automatically according to the planned path. Therefore, the AGV can achieve the inspection of tunnel shield segments by following the planned route.

[0010] In a preferred embodiment, the present invention can be further configured such that: the number of the first industrial slide rails is two, and the top of the first industrial slide rails is provided with a groove adapted to the industrial slider.

Rotating the gimbal knob is used to unlock and fix the rotating gimbal.

[0013] In a preferred embodiment, the present invention can be further configured such that: the omnidirectional ball is enclosed inside the ball table base, the omnidirectional ball is fixed to the second industrial slide rail by a connecting rod, and openings adapted to the connecting rod are provided on both sides of the ball table base.

[0017] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0018] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0019] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0020] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0021] A movable connection refers to a connection in which parts or components are fixed but have relative motion.

[0022] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0023] 1. This utility model can adjust the position and angle of the positioning camera and the measuring camera to better capture images of different parts of the tunnel lining segments, meet the needs of the inspection task for shooting from different angles, and the adjustment operation is simple and the stability is strong.

[0024] 2. The positioning camera of this utility model can adjust its spatial position through the ball mount and the universal ball. After the field of view covers the positioning point area, the universal ball can be locked by the damping handle. The angle and position can be changed in all directions to adapt to the positioning requirements of shield tunnel segments of different shapes and sizes.

[0025] 3. The AGV used in this utility model uses laser navigation, which can create its own map and drive automatically according to the planned path. When inspecting other segments or changing the inspection site, it can continue to be used simply by re-creating the map and reprogramming, making it highly mobile. Attached Figure Description

[0032] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0033] Based on the concept of this application, combined with Figures 1 to 4This invention describes an embodiment of a mobile rapid shield tunnel segment inspection device for tunnel shield segment inspection. Specifically, the mobile rapid shield tunnel segment inspection device is constructed as an integrated structure, comprising three components: an AGV trolley 300, a measuring camera 2, and a positioning camera 1. This invention allows adjustment of the position and angle of the positioning camera 1 and the measuring camera 2 to better capture images of different parts of the shield tunnel segment, meeting the inspection task's requirements for shooting from different angles. The adjustment operation is simple, and the device is highly stable. Furthermore, the positioning camera 1 can be adjusted in space via a ball mount 11 and a universal ball joint 15. After the field of view covers the positioning point area, the universal ball joint 15 can be locked via a damping handle 16, allowing for omnidirectional changes in angle and position to adapt to the positioning requirements of shield tunnel segments of different shapes and sizes.

[0034] Combination Figures 1-4 As shown, the present invention provides a mobile shield tunnel segment rapid inspection device, including an AGV trolley 300, a base 200 fixedly connected to the top of the AGV trolley 300, a platform base plate 3 fixedly installed on the top of the base 200, a projector 12 installed in the middle of the platform base plate 3, a first industrial slide rail 4 fixedly installed on both sides of the platform base plate 3, an industrial slider 7 slidably connected on the first industrial slide rail 4, a rotating gimbal 5 detachably fixed on the top of the industrial slider 7, and a measuring camera 2 detachably fixed on the top of the rotating gimbal 5.

[0035] A raised shaft 10 is fixed on one side of the top of the platform base plate 3. A ball table seat 11 is fixedly installed at the top of the raised shaft 10. A universal ball 15 is rotatably installed inside the ball table seat 11. A second industrial slide rail 14 is fixedly installed on the top of the universal ball 15. A positioning camera 1 is slidably connected to both ends of the second industrial slide rail 14.

[0036] Regarding the technical solution of this embodiment, there are two first industrial slide rails 4. The top of the first industrial slide rail 4 is provided with a slide groove that is adapted to the industrial slider 7. The slide groove is adapted to the industrial slider 7, which can ensure the straightness and accuracy of the industrial slider 7 when sliding on the slide rail, so that the measuring industrial camera can move and measure according to the predetermined trajectory and position, avoiding measurement errors caused by uneven sliding or position deviation.

[0037] Regarding the technical solution of this embodiment, the top of the industrial slider 7 is fixed with an adapter plate 6 by bolts. The industrial slider 7 is fixedly installed with the rotating gimbal 5 through the adapter plate 6. A slide rail handle 8 is threadedly connected to one side of the industrial slider 7. By turning the slide rail handle 8 to unlock the industrial slider 7, the industrial slider 7 can be moved to an appropriate position on the first industrial slide rail 4. Then, the slide rail handle 8 can be tightened to fix the industrial slider 7. This fixing method is convenient to operate and can adjust and lock the position of the industrial slider 7 at any time according to actual needs, ensuring that the industrial slider 7 can be stably fixed in any required position, providing stable support for the measuring industrial camera. Furthermore, by adjusting the position of the industrial slider 7 on the slide rail and the angle of the rotating gimbal 5, the position and attitude of the measuring industrial camera can be flexibly changed, enabling the detection device to better adapt to various complex and changing detection scenarios and improving the versatility and adaptability of the detection device.

[0038] Regarding the technical solution of this embodiment, a connecting plate 9 is fixedly connected to the top of the rotating gimbal 5, and the measuring camera 2 is fixed to the connecting plate 9 by bolts. A gimbal knob 17 is rotatably connected to one side of the rotating gimbal 5. Rotating the gimbal knob 17 is used to unlock and fix the rotating gimbal 5. The rotating gimbal 5 can realize the rotation adjustment of the measuring camera 2 within a certain angle range. Since the rotating gimbal 5 and the measuring camera 2 are connected by the connecting plate 9 and bolts, this structure can ensure the connection is stable while allowing the measuring camera 2 to change the shooting angle as the rotating gimbal 5 rotates. By rotating the rotating gimbal 5, the field of view of the measuring camera 2 can be easily adjusted to better capture images of different parts of the shield tunnel segment and meet the needs of the inspection task for shooting from different angles.

[0039] In this embodiment, the omnidirectional ball 15 is enclosed inside the ball table base 11. The omnidirectional ball 15 is fixed to the second industrial slide rail 14 by a connecting rod. Both sides of the ball table base 11 have openings that match the connecting rods. A damping handle 16 is rotatably connected to the side wall of the ball table base 11. Rotating the damping handle 16 is used to unlock and fix the omnidirectional ball 15. The omnidirectional ball 15 is enclosed inside the ball table base 11. This structure allows the omnidirectional ball 15 to rotate in multiple directions within the ball table base 11. The omnidirectional ball 15 is connected to the second industrial slide rail 14 by the connecting rod, so that the second industrial slide rail 14 and the components installed on it (such as the positioning industrial camera) can flexibly adjust their posture in space. The openings on both sides of the ball table base 11 provide sufficient space for the connecting rod to meet the adjustment requirements in multiple degrees of freedom. This means that the positioning camera 1 can change its angle and position in all directions to adapt to the positioning requirements of shield tunnel segments of different shapes and sizes.

[0040] The damping handle 16 on the side wall of the ball mount 11 allows for easy unlocking and securing of the gimbal 15. When adjusting the position and angle of the positioning industrial camera, simply release the damping handle 16, and the gimbal 15 will drive the second industrial slide rail 14 and related components to adjust their spatial position. After adjusting to the appropriate position, rotating the damping handle 16 will secure the gimbal 15, thus maintaining the stability of the positioning industrial camera. This rapid locking and unlocking mechanism greatly improves the adjustment efficiency of the detection device and reduces the time spent adjusting the equipment.

[0041] Regarding the technical solution of this embodiment, an industrial slider 7 is slidably connected inside the second industrial slide rail 14. An adapter plate 6 is fixed to the top of the industrial slider 7 by bolts. The industrial slider 7 is fixedly installed to the rotating gimbal 5 through the adapter plate 6. A slide rail handle 8 is threadedly connected to one side of the industrial slider 7. Tightening the slide rail handle 8 makes it press against the side wall of the first industrial slide rail 4 to realize the fixing and unlocking of the industrial slider 7. The industrial slider 7 can slide on the second industrial slide rail 14, thereby conveniently adjusting the position of the rotating gimbal 5 and the positioning camera 1 on the slide rail. This allows the detection device to flexibly adjust the position of the positioning camera 1 according to the shield tunnel segments of different sizes and shapes, so as to better capture the images of the tunnel segments and meet the needs of the detection task for shooting at different positions.

[0042] In this embodiment, a connecting plate 9 is fixedly connected to the top of the rotating gimbal 5. The positioning camera 1 is fixed to the connecting plate 9 by bolts. A gimbal knob 17 is rotatably connected to one side of the rotating gimbal 5. Rotating the gimbal knob 17 is used to unlock and fix the rotating gimbal 5. The rotating gimbal 5 can realize the rotation adjustment of the positioning camera 1 within a certain angle range. Since the rotating gimbal 5 and the positioning camera 1 are connected by the connecting plate 9 and bolts, this structure can ensure the stability of the connection while allowing the positioning camera 1 to change the shooting angle as the rotating gimbal 5 rotates.

[0043] It should be noted that in some inspection scenarios, the surface of the tunnel lining segment may have reflections, shadows, or other factors that affect image quality. The pattern projected by the projector 12 can enhance the contrast of the image and make the features of the segment surface more clearly visible. This enhancement helps to improve the quality of the image captured by the measuring camera 2, thereby improving the accuracy of the measurement results.

[0044] Specifically, when testing is required, the measuring camera 2 is first installed on the first industrial guide rail. The industrial slider 7 is unlocked by turning the slide rail handle 8, allowing it to move to the appropriate position on the first industrial slide rail 4. Then, the slide rail handle 8 is tightened again to secure the industrial slider 7. This fixing method is convenient and allows for easy adjustment and locking of the industrial slider 7 as needed, ensuring stable fixation at any desired position. Next, the gimbal knob 17 is turned to rotate the gimbal 5. Rotating the gimbal 5 allows for convenient adjustment of the measuring camera. The field of view of machine 2 is adjusted to better capture images of different parts of the tunnel lining segment, meeting the needs of the inspection task for shooting from different angles. Then, the damping handle 16 is rotated, so that the universal ball 15 can rotate in multiple directions within the ball seat 11. This allows for flexible adjustment of the orientation of the positioning camera 1 in space, changing the angle and position in all directions to adapt to the positioning requirements of tunnel lining segments of different shapes and sizes. Then, the AGV trolley 300 is started. Its navigation method is laser navigation, which can create its own map and drive automatically according to the planned path. Therefore, the AGV trolley 300 can achieve the inspection of tunnel lining segments by walking along the planned route.

[0045] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the mobile shield tunnel segment rapid inspection device provided by this utility model.

[0047] A raised shaft 10 is fixed on one side of the top of the platform base plate 3. A ball table seat 11 is fixedly installed at the top of the raised shaft 10. A universal ball 15 is rotatably installed inside the ball table seat 11. A second industrial slide rail 14 is fixedly installed on the top of the universal ball 15. A positioning camera 1 is slidably connected to both ends of the second industrial slide rail 14.

[0048] The working principle and usage process of this utility model are as follows: When testing is required, firstly, the measuring camera 2 is installed on the first industrial guide rail. The industrial slider 7 is unlocked by turning the slide rail handle 8, allowing it to move to the appropriate position on the first industrial slide rail 4. Then, the slide rail handle 8 is tightened again to fix the industrial slider 7. This fixing method is convenient to operate and allows for adjustment and locking of the industrial slider 7 as needed, ensuring stable fixation at any desired position. Then, the gimbal knob 17 is turned to rotate the gimbal 5. By rotating the gimbal 5, the gimbal can be easily... Adjust the field of view of the measuring camera 2 to better capture images of different parts of the tunnel lining segment and meet the needs of the inspection task for shooting from different angles. Then, rotate the damping handle 16 so that the universal ball 15 can rotate in multiple directions within the ball seat 11. This allows for flexible adjustment of the orientation of the positioning camera 1 in space, changing the angle and position in all directions to adapt to the positioning requirements of tunnel lining segments of different shapes and sizes. Then, start the AGV trolley 300, which uses laser navigation and can create its own map and drive automatically according to the planned path. Therefore, the AGV trolley 300 can achieve the inspection of tunnel lining segments by walking along the planned route.
